We use DiskBench to time a 28.6GB block (9,882 files in 1,247 folders) of mostly incompressible random data, as it's transferred from our OS array, to our test drive/array. We then read from a 6GB zip file that's part of our 28.6GB data block, in order to determine the test drive/array's read transfer rate. The system is restarted prior to the read test to clear any cached data; insuring an accurate test result.

Write Transfer Rate

A 507 MB/s write transfer rate is the second best we've seen to date. Seagate's 600 series managed a 2MB/s faster transfer rate, but that array has twice the capacity of our Q Series Pro array, which does in fact give it a slight advantage over the Q Series Pro array. A similar capacity 600 series array churns out 493 MB/s in this test.

Read Transfer Rate

An 873 MB/s read transfer rate is again the second best we've seen to date. This time, our Chronos array manages to win by a mere 6MB/s.

Our data transfer test is definitely where the rubber meets the road. We're transferring a huge chunk of random incompressible data. This is where everything we've seen so far comes together with actual data. There is no way for a drive manufacturer to "optimize" for this test. This test is an absolute validator of our trace based testing. Our Q Series Pro array does have the best all-around performance transfer rates we've achieved to date, and takes the performance crown from our Samsung EVO array.
